The cornet à pistons was extensively imported, and saxhorns were introduced by the Distin family in 1844, very soon after their development by Sax; they became immediately popular1. British makers made their own versions of the French instruments, and at the same time cheaper instruments made in France and Germany were widely imported2. Although the majority of the valved brass instruments used in Britain, not least in the popular brass band movement, owe much to continental invention, British makers were not idle, either in inventing and improving valve designs or in producing distinctive models of valved instruments. In this essay we discuss some of the valves and instrument models which were developed beyond the experimental phase into production models. VALVE DESIGNS Charles Claggett (born 1737) invented possibly the earliest brass instrument valve, taking out a British patent3 and wrote in 1793 about his chromatic trumpets and horns. Exactly how his invention worked is not known, and there is no evidence that it was put into production by any maker. John Shaw of Glossop took out a patent4 for a valve system that could be applied to any brass instrument. Shaw's “tranverse spring slide” was an early form of double-piston valve. For a trumpet, Shaw used four valves, three ascending and one descending. All were independent: the ascending valves raised the instrument's pitch by a semitone each by cutting out tubing, and the descending valve lowered it by a semitone by adding tubing. Shaw's trombone was equipped with six valves. According to the requirements of different instruments, various numbers of valves - up to six - could be used. The valves were not equipped with any tuning-slides5. No surviving instruments with this type of valve exist, and again there is no evidence that it was put into production by any maker. It is not known if Adolphe Sax was aware of Shaw's invention of independent valves, but in 1852 Sax took out his patents on the independent valve in 1852 and 1859 (the earliest surviving numbered instrument dates from 1 Eugenia Mitroulia and Arnold Myers, The Distin Family as Instrument Makers and Dealers.

A trumpet by Charles Pace of London from the collection of Colonel Thomas Shaw-Hellier, which is on long-term loan to the University of Edinburgh, incorporates an interesting valve type, see Figure 1. Figure 1. Horizontal valves on Pace F trumpet, Edinburgh University Collection of Historic Musical Instruments (3286). Photo: Sabine Klaus. The instrument dates from circa 1840 and stands in 6-ft F with crooks for lower tonalities. As in some other trumpets of the period, the valves are arranged horizontally so that the instrument has a general appearance and playing posture similar to that of the English slide trumpet. However, the valves are a modification of the Stölzel valve with both ends of the valve casing forming part of the windway; the piston is controlled by a touchpiece working in a parallel section of tubing which contains the spring with a connecting piece passing through a slot in the side of the valve casing; the windway is diverted through one of two loops on the side of the valve casing - through the shorter loop of the two when the valve is not operated, and through the longer loop when it is operated. The mechanism of a piston moving in the valve casing which forms part of the windway at both ends, and is controlled by a touchpiece working in a parallel section of tubing containing the spring, was further developed by George Samson in 18627. Again, there is a connecting piece passing through a slot in the side of the valve casing. However, in the Samson valve there is simply an additional loop brought into play when the valve is operated, rather that the alternative loops of the Pace valve. The Samson valve, also known as the “finger-slide valve” was improved and made by Charles Goodison, and sold by Rudall, Rose and Carte.

Samson, Improvements in Valves or Cylinders for Wind Instruments G.B. Patent No 1245, 1862. eleven known surviving instruments with this valve (cornet, eight vocal horns, baritone and a euphonium) are evidence of regular production over a period of some five years. An example is shown in Figure 2. Figure 2. Vocal horn with Samson finger-slide valves. Rudall Rose Carte & Co., London, c 1865. Edinburgh University Collection of Historic Musical Instruments (6095).

This was a solution to the problem of abrupt bends in the windways of valve designs such as the Stölzel valve, which was widely used at the time. Figure 3 shows Shaws drawing from the patent. 8 John Shaw, Improvements in the arrangement and construction of wind musical instruments. G.B. Patent No 7892, 1838. Figure 3. Shaw's swivel valve patent drawing, 1838 (courtesy of Intellectual Property Office). There is a trumpet following this design in the Metropolitan Museum of Art, New York (89.4.2532). The elimination of the abrupt bends is achieved at the expense of a slow action and exposure of the plates to the air when the valve is operated. These problems were subsequently ameliorated: Shaw mentioned in his patent that the fixed and moveable plates could also be made “circular so as never to expose their internal surface to dust or other injury”, and all subsequent extant instruments based on this patent have disc valves9. By 1840 Shaw had entered into an arrangement with the London maker John Augustus Köhler, who made and sold the instruments using his disc valves. Köhler went on to produce more than 1000 disc-valve instruments over some fifteen years under the appellation “Patent Lever”, which refers to the push-rods which actuate the rotation of the discs. In 1842 Shaw published a design in which the loop of extra tubing added by the valve is attached to the fixed disc rather than the moving disc, and two much shorter semicircular loops are soldered to the moving disc; the fixed disc, like the rotating one, now had four rather than two perforations. This lighter valve action was adopted for production models. A subsequent design change was the replacement of watch springs in drums with compression springs: the disc-valve cornopean in Figure 4 is an early examples with watch springs. Forty-eight disc-valve instruments, mostly cornopeans and cornets, are known to survive. No other makers appear to have made instruments following models of Shaw and Köhler, although the principle was subsequently applied to the quick-change valve on cornets (switch valve for B-flat or A) by Ernst Couturier and John Heald in the U.S.A. 9 Frank Tomes, Sabine Klaus and Arnold Myers, Shaw, Köhler and the Disc Valve in Britain.

If one valve lowers the pitch by one semitone, and another valve lowers the pitch by two semitones, operating the two valves together does not add quite enough tube length for three semitones. The problem is worse for valves lowering the pitch by larger intervals. The calculations are more complex than the simple proportions often presented, since valves increase the amount of cylindrical tubing in the windway, and affect the bore profile as well as the air column length.
